GUTTER-BRIDGE.

Patented-Dec. 27,' 1910.

To all whom 'it may concern:-

Be it known that I, CALVIN C. FoUfrs, a

citizen of the United States, residing at Middletown, Butler county, Ohio, have invented certain new and useful Improvements in Gutter-Bridges,l of which the fol-,

lowing is a specification.

My improved gutter-bridge Will be readily understood from the following description taken in connection with the accompanying drawing in which Figure 1' is a vertical transverse section of the bridge: Fig. 2 a vertical longitudinal section of the same: and Fig. 3 aperspective View of one corner of the bridge. y

In the drawing :-1, indicates-the'lower 0r chord member. of the bridge, shown in the` form. of a flat plate: 2, the upwardly and inwardly turned side-edges of the chord` member forming retaining lips: 3, an arch of corrugated metal with its ends engaging under the lips of the chord member, the corrugations oi' the arch extending from lip to lip: 4, arch or other material sup-b ported by the bridge: and 5, the opening througl` .the bridge between the chord and arch. v A

The length of the structure is to be in accordance with the width of the Walk to .be supported by the bridge, and, in addition,'to serving as a mere bridge, the length 'may bc prolonged to anyv extent desired to form a sewer conduit.. Such conduits of considerable length may be formed of compara'tivelyA short sections connected `together at their ends, as by riveting, though then .form is such that for buried conduitsno riveting is essential, itbeing 'suliicient to let the end of one section enter theend ofthe succeeding scctionthe corrugations causing the sections to lock together sutliciently for all practical purposei It -will be "'observed that" lhis structure, considered as a'gutter-bridge or as a conduit, calls for no extra fastenings, that is to say, the arch maybe shipped in flat form, or

in curved forms nested Vmgether'and later assembled Wlth' the comparatively flat chords which may be shipped in fiat form. Again, the 'absence of rivets or the like connectingthe arch with the chord renders possible the endwisc connection of two of the sections with great facility itl being only necessary to lay the chord end to endand then, after the contiguous ends of the two arches have been placed inoverlapping rey lation, springboth of the arches inward to enter between the lips of the chords, both arches then expanding to engage under the lips. It is to be further observed that the side-edges ofthe arch-member are left in their natural condition, or unlianged, and that the upturning of the lips of the basemember are at such an angle to the basemember that the side edges of the arch will catch under 'them and be securely held without the necessity for any Hanging of the arch, and the construction is' such that the parts will go together satisfactorily even in case ofp'such bending and denting as is apt to occur in loosely-shipped sheet metal parts of this general character.

I claim l., A gutter bridge or conduit comprising, Y

an ang 'e-lnwardly from the vertical, and a transversely corrugated sheet-metal archmember having its corrugated side edges engaging under said angular lips, combined substantially as set forth.

2. A sheet metal pipe .including a longitudinally fiat section and an annular corrugated opposite section with overlapping edges, the edges of the fiat section being crimped to fit the opposite section, combined substantially as set forth.

3. A sheet metal pipe including a flat chord section having edges bent to form an angle and a corrugated arch-sect ion having its edges abutted into the angles formed by the edges of the chord section, the edges of' the cho'rd section being shapedL to tit en'ga'ging portions of thearch-section.

4Q A sheet metal pipe including a fiat secltion and anannularly corrugated opposite section, with overlapping edges.

'5. A sheet metal pipe including a flat and an annularly corrugated opposite section joined togetherfat the edges.

6. A sheet metal pipe' including a. iiat section and an annularly corrugated opposite section, the edges of one section being flanged and the edges of the other section being abutted in the angles of the flanges.

7.l A sheetwmetal pipe including a iiat secsection With overlapping dges, tlle edges lower portions of said top. ofone sectionbeing shape to fit t e other Section v l CALVIN C. FQU lb.

tion and -an annularly corrugated opposite said side flanges arranged to overlap the.
